Our guest today is Fujimoto Yasushi,

00:10

the developer of an ultra-high-pressure washer.

00:16

Graffiti vandalism is a persistent problem around the world.

00:20

In many cases, those affected have little choice but to bear it.

00:27

Fujimoto's ultra-high-pressure washer is capable of

00:30

removing graffiti with ease.

00:35

Boasting strong cleansing power without the use of chemicals or detergents,

00:39

the innovative cleaning system is safe and eco-friendly.

00:47

The ultra-high-pressure washer is also being deployed overseas.

00:52

It helped remove graffiti from a palace in Indonesia.

00:58

How did Fujimoto develop this pressure washer?

01:01

And what drives his commitment to graffiti removal?

01:08

Graffiti refers to illicit markings in public spaces.

01:12

Some of it is considered "graffiti art" or "street art."

01:15

However, graffiti is first and foremost a crime.

01:19

And if the city allows this criminal act to go unchecked,

01:23

even if it is a minor offense,

01:25

you foster the sense that the city will turn a blind eye to crime.

01:29

And I don't think that's a good thing.

01:33

It doesn't matter how cool the graffiti looks,

01:36

you have to clean it up,

01:38

and let people know that the crime isn't going to go unpunished.

01:43

On this day, Fujimoto is busy at work under a highway overpass.

01:48

The organization that maintains the road hired him to remove some graffiti.

01:56

It covers a section of the wall about two meters high and six meters across.

02:04

Fujimoto washes the spray paint away with a steady hand.

02:13

In about four hours, the wall returns to its original state.

02:20

Whether it's a concrete wall, store shutter, or a private residence,

02:24

he's able to make them look as good as new.

02:31

His cleaning apparatus consists of a compressor and boiler,

02:34

which are used to spray water heated to 140 degrees Celsius.

02:45

But it's not just hot water.

02:47

He also uses extra-fine baking soda,

02:50

composed of particles about a tenth of a millimeter in diameter.

02:55

The baking soda and hot water are combined in the nozzle as a powerful spray,

03:00

with the small particles essentially scraping the paint off of surfaces.

03:06

What's more, the baking soda is alkaline,

03:09

which neutralizes the acidity of paint to aid its removal.

03:14

Generally speaking, when it comes to removing graffiti,

03:17

the most common way it's been done is to use organic solvents

03:21

like paint thinner and benzine

03:23

to melt the lacquer spray paint and remove it.

03:27

If you melt it with thinner, naturally,

03:30

you end up inhaling fumes, so you feel nauseated and get headaches.

03:35

Meanwhile, with my method, you use baking soda,

03:38

which is a leavening agent used in food.

03:41

It makes bread rise and cakes spongy.

03:44

We use food-grade baking soda. It's safe to ingest.

03:49

Because all we're spraying is water and baking soda,

03:53

it's safe for the person operating the device,

03:55

as well as nearby people and plants.

03:59

Since Fujimoto perfected his apparatus in 2011,

04:02

it's been used to remove graffiti from over 500 locations in Japan.

04:09

Word of Fujimoto's services spread overseas,

04:12

and in 2016 he received a request to come to Indonesia.

04:17

He was asked to remove graffiti from a ten-meter stretch of wall in Jakarta.

04:24

I got the request via email.

04:27

At first, I thought it was a joke.

04:29

But I was also interested in helping out with graffiti removal overseas.

04:36

Fujimoto and his team worked in searing 40-degree heat.

04:42

Here's the result of two days of work.

04:47

Fujimoto also went to a palace built in the 18th century.

04:53

He was asked to help remove graffiti that had been brazenly sprayed

04:57

on one of the castle walls.

05:01

This was something built to be left behind for future generations.

05:06

To vandalize it was a selfish act

05:08

showing no regard for the people who made it.

05:13

This wall was restored in just one day.

05:19

For that job, I was approached by the Indonesian royal family.

05:23

They were so happy.

05:25

It was so hot working out there,

05:27

but seeing their reaction rejuvenated me -

05:30

made me glad to have gone all that way.

05:34

Fujimoto was born in 1970 in Otsuki, Yamanashi Prefecture.

05:40

His family ran an automobile sheet metal painting business.

05:44

Fujimoto learned the trade from his father.

05:50

When Fujimoto was 34,

05:52

his father died in a traffic accident.

05:57

Fujimoto took over the family business,

06:00

only to learn that it was burdened with debt.

06:04

Thirty-seven million yen in debt.

06:07

For about six months after I took over, my wife stuck with me,

06:11

but then all of a sudden, she asked for a divorce.

06:15

I think she couldn't come to terms with the fact that

06:17

we'd been saddled with this enormous debt essentially overnight.

06:23

Fujimoto was riding the train home after a business trip to Tokyo

06:27

when he saw something that shocked him.

06:30

From the train, I saw so much graffiti on the walls.

06:34

It was a shock. I couldn't believe my eyes.

06:37

It was like a mark of anarchy, and I was shocked to see it unaddressed.

06:41

Wasn't anyone complaining?

06:45

I immediately got the feeling that this was giving people trouble.

06:49

And then I thought, the graffiti is made using lacquer spray paint.

06:53

I'm always painting sheet metal for cars.

06:57

I think maybe I can remove that graffiti.

07:02

I thought that if I could erase it, people would be happy.

07:05

And what's more - let's be honest - I knew it could lead to more work.

07:10

Fujimoto spray painted a concrete block and began tests to remove the paint.

07:16

First, he applied the company's thinner.

07:20

I tried to wipe it clean, but it didn't work at all.

07:24

Instead of going away, the paint spread.

07:27

Concrete is like pumice. It's a porous material.

07:31

It has holes in it.

07:32

And as the paint thins, it seeps into those holes.

07:36

So it doesn't go away, it just melts.

07:39

Ultimately, I found that with that method it just took too much time,

07:43

plus your hands got chapped, and the fumes gave you headaches.

07:46

It became clear thinner wasn't right for the job.

07:51

Next, Fujimoto tried a commercial high-pressure washer.

07:55

Out of consideration for the environment,

07:57

he decided not to use any chemicals.

08:00

But the water wasn't enough to remove the paint.

08:06

Then he remembered something he'd seen growing up.

08:13

I remembered seeing my mother and other people around the neighborhood

08:16

cleaning burnt pots by boiling baking soda in them.

08:21

That's when it hit me that maybe if I used hot water to spray baking soda,

08:26

it would be effective in removing paint and residue.

08:30

Fujimoto bought a compressor and boiler, connecting them

08:34

so that hot water and baking soda were mixed together in the nozzle.

08:38

He tried blasting away the paint.

08:41

But the first tests were failures.

08:44

He realized the problem was the ratio of water to baking soda.

08:49

You'd think the more baking soda, the better,

08:51

but that turns out not to be true.

08:54

It was tough to figure out the perfect blend.

08:58

But our sheet metal business was slow,

09:00

so I worked on the washer all day, along with two other employees.

09:05

On the fifth day, we got everything fine-tuned just right.

09:08

It removed graffiti so easily we couldn't believe it at first.

09:13

With that perfect ratio,

09:15

Fujimoto had a highly effective cleaning machine.

09:19

He says using hot water helps create a powerful steam.

09:23

By heating the water with the boiler, it gets excited. It wants to get out.

09:28

You can cut through a daikon radish.

09:31

Here's a demonstration.

09:43

Fujimoto perfected his ultra-high-pressure washer in 2011.

09:49

Word of its unmatched cleansing power quickly spread

09:51

as he traveled around Japan removing graffiti.

09:58

Clients appreciated the fact that his method was eco-friendly.

10:02

He received an influx of inquiries - not just for graffiti removal,

10:06

but to clean the dirt off of exterior walls and water tanks,

10:10

to wash moss off of tombstones, and more.

10:16

The work even allowed him to pay off his late father's debt.

10:22

He says that the more graffiti he removed,

10:24

the stronger his conviction grew.

10:28

Often when we erase graffiti,

10:30

we bring up the gray paint underneath,

10:32

and when we blast that away, we find another layer of graffiti.

10:36

Sometimes it's three layers of graffiti.

10:39

The gray paint ends up becoming a canvas for more graffiti.

10:43

Then they paint over that with more gray, which leads to more graffiti.

10:47

Finally, they've had enough and give us a call.

10:49

Often when we remove graffiti, we find multiple layers.

10:54

We end up removing all the graffiti as well as all the gray paint.

10:58

That restores the surface to its original form.

11:02

And when you go that far, funnily enough,

11:05

recurrence is relatively rare.

11:09

So, what I'm trying to do is not so much remove graffiti as

11:12

erase all traces of graffiti.

11:15

After we're done with a surface,

11:16

I want it so people can't tell there was ever graffiti there.

11:21

Fujimoto says the reason he doesn't use chemicals

11:24

is because he wants to minimize damage.

11:27

He believes he can restore surfaces using only hot water and baking soda.

11:34

Restoration is my mission.

11:36

My hope is that by returning things to their original state,

11:40

I can contribute to the community, to society.

11:45

Hoping to get the apparatus into more people's hands,

11:48

he's hosted training sessions to teach others to use pressure washers.

11:53

In 2017, he founded the Special High Pressure Washing Association,

11:57

which currently has 25 member companies.

12:03

Fujimoto himself receives no royalties from the other firms.

12:09

People often tell me, if you'd kept this a trade secret,

12:13

you could have made more money off the technology,

12:16

you could've had a monopoly over the market.

12:19

People wonder why I go out of my way to teach others,

12:22

or to show the media how we do things.

12:25

I'm spreading the word that you can use a high-pressure washer,

12:29

baking soda, and hot water to remove graffiti.

12:34

I'm doing that to create awareness, to create a market for our services.

12:38

To that end, rather than try to keep the market to ourselves,

12:42

I actively teach others how to do this, how to do it right.

12:48

I want to help others and create a market.

12:52

As part of the Japanese government's plan to reduce disaster risk,

12:56

large-scale renovations of old concrete structures

12:59

are underway across the country.

13:02

Fujimoto's apparatus will be a key tool,

13:05

as washing the dirt off of surfaces

13:07

makes it easier to spot cracks and defects.

13:12

Concrete structures age, like people.

13:16

And structures across Japan are reaching the end of their lifespan.

13:20

But it's difficult to inspect concrete

13:22

when there's blackened dirt and moss and such accumulated on the surface.

13:28

You can't measure the length of cracks,

13:30

which means you can't measure how cracks develop over time.

13:34

Ideally, you want to restore the surfaces to just their base material.

13:39

That way, you can measure cracks,

13:41

and the next time you can see how much it's grown.

13:44

Then the person doing the inspection can decide

13:47

if it needs to be cracked open.

13:50

There's a responsibility to inspect concrete properly,

13:54

to provide peace of mind and security for the people.

13:57

That's not just true in Japan. It's true around the world.

14:02

(Do you have any words to live by?)

14:11

"The soil does not say, 'I made this flower bloom.'"

14:17

Flowers may be beautiful,

14:19

but without the soil, there'd be no flowers.

14:23

Yet Mother Earth never says, "I made these flowers bloom."

14:28

The soil knows that its calling is to make those flowers bloom.

14:32

Meanwhile, my calling is to remove graffiti and to fix cars.

14:38

Even if I'm able to set an example for young people,

14:42

I would never want to lord it over them.

14:45

I want to remain humble.

14:47

By doing that, I believe I can contribute to the betterment of things.
